For what it's worth, I've been experimenting with the tikzDevice R
graphics device. I have in the preamble of my current document
#+srcname: orgrsetup
#+begin_src R :session *R* :exports none :results none
library(tikzDevice)
org.device <- function(name, ext) {
file <- sprintf("%s.%s", name, ext)
switch(ext,
"png"=png(file, width=480, height=384),
"tikz"=tikz(file, width=5, height=4))
}
org.raw <- function(name, ext) {
file <- sprintf("%s.%s", name, ext)
switch(ext,
"png"=sprintf("[[file:%s]]", file),
"tikz"=sprintf("#+LaTeX: \\input{%s}", file))
}
#+end_src
and then I use
#+begin_src R :session *R* :exports results :results value raw :var
name="filename" :var ext=(csr-org-export-babel-graphics-extension)
org.device(name, ext)
# draw the picture here
dev.off()
org.raw(name,ext)
#+end_src
where csr-org-export-babel-graphics-extension returns "tikz" if the
backend is latex, and png otherwise. This (with a bit more work on the
R side) gives me scalable graphics with fonts matching the PDF
document's fonts going through LaTeX, and acceptable-quality HTML.
(Which is something I've been looking for for the last six years, so I'm
quite pleased at the moment :-)
I hope this helps to provide some ideas.
Cheers,
Christophe
